Heat pumps

Energy-saving, cost-effective, sustainable and with a guaranteed future – those are the principal features associated with a modern, properly installed heat pump. OCHSNER heat pumps offer critical advantages for heating, cooling and hot water heating. And the system is extremely simple:
The heat pump uses ambient heat which is stored in the air, water and ground – natural heat sources. Much of this environmental energy comes from the sun, but heat also comes from deep within the ground. These renewable energies are heated from a low to a higher temperature level by means of sophisticated technology, making them suitable for heating purposes.

How Do The DC Inverter AIR – WATER Heat Pumps Operate

The whole system consists of the external and internal unit. The external unit with evaporator and fan is placed outside and it sucks ambient air. At that moment, liquid coolant is injected to the external unit via the expansion valve. Flowing air heat is transferred to the coolant in the evaporator. So its state changes to gas state. The coolant in gas state proceeds to the internal unit, concretely to the compressor where it is pressed. While the coolant is pressed in the compressor, the pressure increases and so increases the temperature. In this way, the original low-potential heat of the coolant taken from the external air increases to the level suitable for heating or water heating. The coolant of high temperature then proceeds to the condenser and transfers heat to water of lower temperature there. In this way, the coolant is cooled down and condensation occurs. Heated water that accepted heat from the coolant goes to radiators or floor heating and emits the heat to a room. The condensed coolant passes via the sub-cooling exchanger to the external unit and the whole cycle repeats.

Exchanger (high-pressure part), the gas cools down and condensates
2. Expansion valve, the liquid expands and cools down
3. Evaporator (low-pressure part), the liquid evaporates and changes its state to gas
4. Compressor, the gas is pressed and it heats up

Red section = high pressure
Blue section = low pressure


Heat pumps operate on the same principles as a refrigerator - except that the process is reversed. A heat pump extracts some of the thermal energy stored in the ground or in the groundwater (this stored energy is constantly replenished) and converts it into space heating.

The system works all year round. Below a certain depth the ambient temperature and the temperature of the groundwater are no longer affected by seasonal changes.

Passive Cooling

During the summer, your Weider heat pump can be combined with an additional cooling set (optional accessory) to reduce the room temperature by around 2-4 °C. The water in your underfloor heating system absorbs the thermal energy, and this is then dissipated into the ground via the heat pump. Only the economical recirculation pumps need to run for this to work, so the compressor can remain switched off and does not consume any electricity.

DC Inverter Heat Pump Water Heaters Features:

1. DC Inverter Air to Water Heat Pump adopt DC Inverter compressor,
DC Inverter motor,When the system start,the compressor is running rapidly to make the room temperature reach the setting temperature,When the room reach its setting temperature,the system will keep its setting temperature effectively and accurately by controlling the compressor and motor's running speed,no need use more electricity.

2.DC Inverter technique achieve the machine's big power and high energy efficiency rate,COP 30% Higher than Normal heat pump,It has features of good running economy and work stability.

3. Designed as Split Type , Indoor Unit and Outdoor Unit be Connected by Copper pipe,Installation With Simple,Flexible and Conveniently ,The Indoor Unit can be Installed in Kitchen, Bathroom or basement, Ensuring less Energy loss, Also Prevent Water Pipes From Freezing in Cold Winter and sun Exposure in hot Summer.

4. Indoor Unit Mainly Components Includes:SWEP Plate Heat Exchanger,Controller,Wilo & Grundfos Cycle water Pump,Differential Pressure Flow Switch,Electric Three Way Valve, Auxiliary Heating and so on parts.

5. Outdoor Unit Mainly Components Includes:DC Inverter Compressor,Evaporator,Panasonic DC Inverter Motor,Additional Plate Heat Exchanger,Controller,Expansion Valve,Four way valve,Refrigerant valve and De-Ice Heater so on parts.
6. Using and MITSUBISHI Rotary Twin-Cylinder DC Inverter Compressor and HITACHI DC Inverter EVI System Scroll Compressor ,Green Environment, High-Efficiency,Providing Wonderful Performance and Reliability.
